SPECIFICATION forming part of Letters area N... 743,868, dated November10, 1903.

Application filed November 20,1902. serial Ne. 132,067. a. model.)

To all whom it may concern:

Be it known that 1, JOHN W. HEATON, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented certain new andiuseful Improvements in Stackers, of whichthe following is a specification.

This invention relates to improvements in separators, clover-hullers,and the like, and

has special reference to the means for convey ing out in apracticalmanner the application of compressed air at or near the end of the tubeto draw the straw' through the tube by sucti0n,as provided in my PatentNo. 711,964,

issued October 28, 1902.

Referring to the accompanying drawings,in

which like characters indicate like parts, Figure 1 is a side elevationof my invention in operative position on a separator, and Fig. 2 is aview in the direction of the arrows from the line2 2 of Fig. 1.

3 is a separator of any usualor well-known construction, and 4 theriddlesfromwhich the straw is discharged into the hopper 5, secured in afixed manner to the frame of the machine under the discharge end'of saidriddles. r l

Mounted on a suitable lower platform 6 of the separator-body is thebase-plate 7, upon which is the circular plate 8, which is centrallypivoted to the plate 7. The plate 8 rests on balls 8 and has peripheralcogs which are engaged by the cogs of a pinion 9 of a short verticalshaft mounted in a suitable box 10, supported by-the side of platform 6.The lower shaft end has the hand-wheel 11, by which the pinion isrotated torotate the plate 8. The latterhas the two parallel standards13 13, between the upper ends of which the tubular discharge or chute ispivotally mounted. The lower or inner end 14 of this chute is curved toprovidea lateral inlet, and this inlet is connected by an expansibleportion 15, of air-tight construction, like the sides of a bellows,whichallows for the vertical adj ustment of the chute on the above-mentionedby the teeth of pinion 17 on shaft 18. The

latter shaft, being supported by the standards 13 and provided with thecrank 19, provides means for vertically adjusting the part.

14. The latter will have themanhole 20 for ready access to the interiorin case of clogging or other occurrencemaking such access desirable. Thesaid part 14, terminating at the line a, will preferably be made ofcastiron to insure rigidity and strength, although other material may beused, and the section 21 of the chute will be secured to the outer orend a of said cast portion. An outer section 22 of the chute willtelescope over the section 21. Secured in a firm and substantial mannerto the part 14 is a bar 23, having the sprocket-wheel 24 and crank 25mounted on a shaft at its lower end and a sprocket-wheel 26 mounted atthe upper end of said bar. These two sprocket-wheels are connected bythe endless link belt 27, which is secured at 28to the outer section 22of the chute. By

turning the crank 25 the outer section of the chute will be moved out orin, depending on 2 socket 29, bolted to section 14, in which socket theend of the bar 23 is removably placed, and the section 21 of the chutewill preferably be removably secured in a like manner to the part 14 atct,whereby said bar and outer members of the chute maybe disconnectedand placed upon the top of the separator for transportation or storage.

The expansible or bellows portion 15 will be annular in shape andconnected with an annular flange on the outlet of the funnel or hopper5, and the jointthus provided will permit of free rotary adjustment ofthe chute.- inlet occasioned by the side movement of the chute inbuilding a stack. These annular rims or flanges have additionalinterlocking flanges, as shown in Fig. 1, or they may be retained inproper mutual relation by other suitable means.

Located at any convenient part of the separator or stacker mechanism isthe tank 30, which is supplied with compressed air through pipe 31 byany suitable means. This tank is connected by pipes 32 32 with theinjectornozzles 33 33, located on opposite sides of the outer section ofthe chute adjacent to the outer end of said section and dischargingcompressed air into said chute, so as to create an induced draft orsuction upwardly and outwardly through said chute in the manner asdescribed and claimed in my former patent, hereinabove referred to. Thedirection of the delivery of the straw from the discharge end of thechute is determined by the hood or deflector, as shown, in which themain body portion is an inverted- U-shaped frame or bail 34, whichstraddles the outer end of the outer section of the chute and is pivotedat its ends at 35 like the bail of a bucket to cars depending from saidchute-section. This bail is somewhat larger than the diameter of thechute, so as to allow of a limited swinging adjustment. It is drawn in adownward direction by the spring 36. This is overcome by a cable 37,attached to the top of the bail, or

rather to an arm extension 38 therefrom,which passes thence around apulley 39, located farther out on the chute, and thence back to aWindlass 40, mounted on the threshing-machine body in easy reach of anoperator on the ground below. The bail or frame 34 has theoutwardly-projected and curved prongs or rods 41, which direct the strawissuing from the mouth of the chute without interfering in any way withthe free escape of the air associated with it. While I regard this openconstruction of hood as preferable, I am aware that a solid outer wallwould change the direction of the air-current carrying the straw andunder some circumstances be preferable. For ordinary and general serviceI consider that the open formation is the more efficient; butIdonotdesire tolimit my invention to either form.

Having thus fully described my invention, what I claim as new, and wishto secure by Letters Patent, is-

1. In a stacker, a chute pivoted to allow of vertical adjustment of itsouter end and having an inlet at or adjacent to its inner end, a fixedhopper to receive from the machine the material to be stacked and anexpansible conduit connecting the hopper with the chuteinlet.

2. In a stacker, a hopper through which the material to be stacked mustpass, said hopper having an annular outlet, a chute having a lateralinlet adjacent to its inner end, said chute being pivoted to allow ofthe vertical adjustment of its outer end and also lateral adjustment ofsaid outer end about an axis through the center of said annularhopperoutlet and an expansible conduit connecting the hopper with theinlet to the chute.

3. In a pneumatic stacker, a tube through which the material to bestacked is discharged, a bail pivotally secured atits ends to the lowerwalls of the chute adjacent-to the discharge end of the chute or tubeand having a swinging adjustment on said pivots said bail having curveddeflectors which project into the path of the discharge to change thedirection of the discharge.

4. The combination with a tubular discharge of a bail pivoted at itslower ends to the lower portion of the'tube, said bail having curvedrods or prongs, a spring to move the bail in a direction to raise theprongs and a cable attached to the bail and passing first around a fixedpart on the side of the bail opposite the spring and carried thence inthe direction of the spring to the bottom of the tube, and means forreeling up and holding the cable.

5. In a stacker, or expansible conduit a chute pivotally mounted so asto have vertical and lateral adjustments and having an inlet through itsupper side connected with said conduit whereby the material to bestacked will be fed downwardly into said chute, said chute being inremovable and detachable sections whereby the outer parts may be removedfor storage or transportation.

6. In a staoker,a pair of standards mounted on a circular base said basehaving peripheral cogs and being pivotally secured, a supporting-plateto which said base is secured, ballbearings between said plate and base,a shaft having a pinionat one end to engage the peripheral cogs of thebase, means for rotating the shaft,achute pivotallysecured atits lowerend between said standards, said chute being in telescoping sections andhavinga top side inlet, a fixed hopper over said inlet and expansibleconnections between the hopper and inlet, an adjustable deflector orhood on the outer end of the chute and means for moving thechute-sections longitudinally of each other to change the length of saidchute.

In witness whereof I have hereunto set my hand and seal, atIndianapolis, Indiana, this 13th day of November, A. D. 1902.
